public void RpTypeBind() {
//数据源绑定的是一张表 this.rptypelist.DataSource = Letao.BLL.ProductCategory.GetDataSet(0).Tables[0]; this.rptypelist.DataBind(); } //在绑定分类品名时,绑定分类下的产品 public void rptypelist_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rptProduct = (Repeater)e.Item.FindControl("rpquestionlist"); //找到分类Repeater关联的数据项 DataRowView rowv = (DataRowView)e.Item.DataItem; //提取分类ID int CategorieId = Convert.ToInt32(rowv["ID"]); //根据分类ID查询该分类下的产品,并绑定产品Repeater rptProduct.DataSource =Letao.BLL.ProductCategory.GetDataSet(CategorieId).Tables[0]; rptProduct.DataBind(); } }
备注:绑定大类时返回的是表结构
